<p>The present invention relates to a compound that changes colour in response to acids, alkali liquid chemicals and toxic gases, and the use thereof. The colours of acids, alkali liquid chemicals and toxic gases are mostly transparent like water (H2O), and thus it is difficult for a person to immediately sense the danger thereof. For this reason, the risk of accidents is high, and a number of accidents associated with liquid chemicals and toxic gases occur at industrial sites. To solve this problem, the present invention provides a manufacturing method for a compound for detecting acid, liquid chemical and toxic gas leaks, and the use of the compound, wherein a paint is applied or a tape is wrapped on areas that have the potential for liquid chemical and gas leaks, the paint or tape containing a special reaction compound for detection that changes colour from yellow to red or from white to red if there is a liquid chemical or gas leak. Thus, the first person who finds the colour change can take quick action.</p> |
